HORSESHDE.

SPECIFICATION forming part of Letters Patent No. 298,907, dated May 20, 1884:. Application filed Match 20, 1884. (N0 model.)

To ctZZ whom, it may concern Be it known that I, GEORGE E. SPRINKLE, a citizen of the United States, and a resident of South Whitley, in the county of Whitley and State of Indiana, have invented certain new and useful Improvements in Horseshoes; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to that class of horseshoes which are provided with detachable toe and heel calks; and it consists in certain improvements in the construction of the same, the principal objects of which are to so attach the said calks that they shall be prevented from being wedged fast into the body of the shoe, and that consequently they may be readily removed when it is desired to substitute new calks for those which are old and worn out.

For the accomplishment of these ends my invention consists in the improved construction and arrangement of parts which will be hereinafter fully described, and particularly pointed out in the claims. V

In the drawings hereto annexed, Figure 1 is a perspective view of the toe-calk. Fig. 2 is a perspective view of one of the heel-calks. Fig. 3 is a bottom view of a horseshoe, showing the same before the calks have been placed in position, the dottedlines indicating the recesses adapted to receive the fastening-lugs projecting from the shanks of the calks. Fig. 4 is a front view of the shoe with the calks in position. Fig. 5 is a horizontal sectional view on the line at w in Fig. 4, and Fig. 6 is a horizontal sectional view on the line y y in Fig. 4..

The same letters refer to the same parts in all the figures.

Referring to the drawings, A designates the body of the horseshoe, which is, in the main,

of ordinary construction, and provided near its front or toe point with a somewhat diagonal recess, B, formed in the under side of the shoe,and provided in its bottom part with wedge-shaped recesses G 0, extending 011 the opposite sides and in opposite directions from the main recess B.

D D are screw-holes extending from the outer and inner sides of the horseshoe to the ends of the recess 13, and registering with the unrecessed portion of the same. The ends or heels of the horseshoe are likewise provided with recesses E E, formed in the under side of the same, in a somewhat diagonal position, the bottom parts of said recesses being provided with oppositely located wedge-shaped extensions or sub-recesses F F. The screwholes in this case, however, extend from the end and outer side of the horseshoe, respectively, to the unreccssed portion of the main recess.

G designates the toe-calk, and H H the heel-calks, each of which is provided with a shank, I, the upper end of which is provided on opposite sides with wedge-shaped lugs or extensions J J, adapted to enter and fit in the wedge-shaped recesses of the openings which the shanks of the respective calks are designed to enter.

To adjust the calks, the shanks of the same are caused to enter their respective recesses, after which they are given a slight twist or turn, which will cause the wedge-shaped projections of the shanks to enter their appropriate recesses. The binding-screws are then inserted, which will prevent the wedge-shaped projections from leaving their recesses and the calks from coming out.

From the simplicity of the construction it will at once be evident that the insertion or removal of the calks will be the work of but a moments time. There is absolutely no strain upon either the screws or the shanks of the calks; hence theycannot possibly become wedged fast by any amount of use, and the calks may therefore be easily removed when it is desired to replace them with new ones.

I claim as my invention, and desire to secure by Letters Patent of the United States- 1. The combination, with a horseshoe provided at the toe and heel points with diagonal recesses having wedge-shaped extensions, of the calks provided with shanks having corresponding wedge-shaped extensions, substantially as herein described, and for the purpose shown and specified.

2. The combination of a horseshoe having diagonal recesses at the toe and heel points,

10 extending. wedge-shaped lugs or extensions,

substantially as and for the purpose shown and specified.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

GEORGE E. SPRINKLE.
